Shroomok: Greish myc NOT contam in your case. If you don't see visible growth at all for 1-2 days, then you have mushroom aborts (shroom caps turn black soon). Details: https://shroomok.com/en/wiki/Mushroom_aborts Or maybe just lack of humidity and shrooms stalled a bit. Mild condensation is a sign of high humidity level and/or high evaporation rate, and/or temperature difference between room and your fruiting chamber. Myc looks good, I can't say it's dry. However I'd like to mist the walls of fruiting chamber and check the speed of mushroom growth after misting. Shrooms give you a sign 😉
